B2Mo is a stable, metallic transition-metal boride used primarily in materials research to explore the properties of refractory binary compounds.
About B2Mo
B2Mo is a transition-metal boride characterized by its inherent metallic electronic structure. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration within the molybdenum-boron binary system, making it a subject of significant interest in materials science research. Its structural stability is supported by extensive data across multiple databases, reflecting its importance in the study of hard, refractory materials. The compound is primarily utilized in fundamental research aimed at understanding the relationship between composition, crystal structure, and physical properties in metal-rich borides. Its metallic nature and stability make it a valuable candidate for exploring advanced mechanical and electronic behaviors in high-performance engineering contexts.
Key Properties
Cross-validated computational properties for B2Mo, aggregated across 4 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
